Control ES2 FMintensity with an envelope and FMscaling
In the FMEnvelope setting, you can control the FMintensity with an envelope, generated
by Envelope2. The modulation target is the range that falls between Sine and FM in the
oscillator wave selector. The first Router channel is used for this modulation routing. You
can control a wider range by using additional modulation routings, which have been pre-
prepared for you. All you need to do is set their values. Because these modulations work
without velocity sensitivity, you can set them in the Editor view by moving both the lower
and upper fader halves to their topmost positions.
In Logic Pro, do the following:
Set the second modulation routing to 1.0. You’ll hear how the modulation now “wanders”
through a broader sound range.
Set modulation routings 3 and 4 to a value of 1.0 as well, and listen to the increase in
the sound range.
After these drastic augmentations to the modulation range, the sound becomes uneven
across the keyboard. In the lower and middle ranges it sounds nice, but in the upper key
range the FMintensity appears to be too severe. You can compensate for this effect by
modulating the Osc1 Wave target by keyboard position (kybd) in modulation routings 5
and 6. This results in a keyboard scaling of the FMintensity.
Because the sound range is so vast (due to the four modulations), two modulation
routings are required to compensate for this. Set the lower slider halves to their lowest
positions. Good keyboard scaling is essential for any FMsound.
Use FMDrive and Filter FM to change the tonal color in ES2
The FMDrive setting illustrates how dramatically the character of FMsounds can be
altered when you apply Drive and Filter FM. The results are reminiscent of the feedback
circuits of classic FMsynthesizers.
In Logic Pro, do the following:
Check out different Drive and Filter FMsettings.
Lower the Cutoff Frequency of Filter2 to 0. Envelope2 modulates Filter2. This
modulation routing is already present in the setting.
Create FMsounds with Digiwaves in ES2
In the FMDigiwave setting, a Digiwave is used as an FMmodulator. This results in bell-like
spectra from only two operators. With traditional FMsynthesis, this type of timbre could
normally be produced only with a larger number of sine oscillators.
To create a fatter, undulating, and atmospheric quality to the sound, the polyphonic Unison
mode has been engaged. Filter and amplitude envelopes have been preset to shape the
sound.
